What is Error and its types?
Error :
Deviation from the exact or true value is known as an error.

1. Inherent Errors:
Error that is already present in the statement of problem. These error arises due to limitation of mathematical table or digital computers.
- Data Errors: These errors arise when the data for a problem is taken from an experiment and are therefore of limited accuracy.
- Conversion Errors: These errors arise due to the limitation of the computer to store data.
2.Numerical Errors:
Errors that are introduced during the process of implementation of numerical method.
- Roundoff Errors: These errors are due to the limitation of computer to store data, as error arise when fixed number of digits are used to represent exact number.
- Truncation Errors: Here extra digits are dropped which introduced truncation error. Example : value of pi, ex etc.
